I was wondering about this in another thread ages ago, and I don’t think anyone ever reported clear rules for Taiwan for dealing with other people at home. The best I found at the time - I haven’t looked recently - was some guidelines from New South Wales. Key points from that source about other people:
Separate yourself from the other people in your home
If you are sharing your home with others, as much as possible, you should:
- remain separated from others
- wear a surgical mask when you are in the same room as another person
- use a separate bathroom, if available
- avoid shared or communal areas and wear a surgical mask when moving through these areas.
Make sure that you do not share a room with people who are at risk of severe disease, such as elderly people and those who have heart, lung or kidney conditions, and diabetes.
People who do not have an essential need to be in the home should not visit while you are in isolation.
EDIT: later in the thread, @Icon reported this, source unclear:
Person is not allowed out and about. Absolutely banned from public transport.
Prepare a separate room. Affected person should keep a distance of one meter from others. No hugs, no kisses, no horizontal tango.
Common areas should be disinfected 3 times a day.
One more thing: do not share table to eat. No eating from same bowls.
